' SPEGLFIGATION forming part of Letters Patent N0. 513,398,dated January 23,1894. Application filed March 16, 1893. Serial No. 466,305. (No model) 7 .To all who'm, it may concern:

Be it'known that we, HUGH A. Kmesmm), residing at Belleville, and WHI'I'ING P. SAN- GER, residing at East Orange, in the county 5 of Essex and State of New Jersey, citizens of the United States, have invented new and which the following is a specification. 7 This invention has for its object to increase the accuracy of fire arms and like articles such for example as ordnance or air guns and the invention consists in the novel features pointed out in the following specification and claims and illustrated in the annexed drawings, in -which I Figure 1 is a longitudinal section of a barrel. Fig. 2 is a front elevation of Fig.1. Fig.

3 'is a detail viewof amodification.

. In the drawings the letter A indicates the barrel or body of the device or fire arm and any suitable manner and is firedhby a touchhole or by a ca or fulminate D according to the nature of t e arm or piece.

The barrel or body A is provided with an in front of the charge or cartridge '0. The

inlet E is made to extend from the outside of the barrel or body A in the direction of the discharge or forward "toward the muzzle whereby such inclined inlet will not allow pressure should exist in the bore such-press.- ure-can be confined by'an inwardly opening valve E which will close to prevent escape of the pressure through opening E. V H By experiment we have found the valve F is not essentialbut it is of advantage as above stated. I

' escape through the inlet, as might occur in 'case no valve is used, such pressure will not travel backward toward the attendant or in- A jdividual handling the piece. The outer or In the modification shown in Fig. 3 the outer deflected branch of the inlet is readily formed in a band or strap G clasping the barrel or body. v

The valve D is shown in simple formas a.

ball valve but any suitable well known valve can be used for admitting air whileadapted to confine pressure in the bore.

By providing an air inlet we have found that the recoil or movement of the muzzle which is a disturbing element especially in hand pieces such as pistols, shot guns, fowling pieces and the like is prevented, so, that accuracy is gained, and the carrying distance is also increased, or in other words, the projectile is driven forward with greater force.
